Sophos is seeking a Senior Marketing Manager, Lead Lifecycle & Conversion to join our Global Growth Marketing team and own the strategy for how prospects progress through the buying journey – from initial engagement and qualification through to opportunity and revenue.

This role will bring together lifecycle strategy, nurture, buying signals, lead management and conversion optimization to create more connected, relevant experiences for Sophos prospects. Working across Growth Marketing, Marketing Operations, SDR, Sales and Revenue Operations, you will identify where prospects stall or disengage and develop programs that improve progression, conversion and pipeline outcomes.

This is not a traditional nurture marketing role. We are looking for someone who can think across the entire funnel, use data and buying signals to understand customer behaviour, and build a lifecycle strategy that turns engagement into measurable business outcomes.

• Own and continuously evolve Sophos' global lead lifecycle strategy, from initial engagement through MQL, SAL, opportunity and revenue.
• Map and optimize prospect journeys across key buying stages, identifying friction, leakage and opportunities to accelerate progression.
• Establish clear lifecycle performance metrics and use funnel data to prioritize opportunities for improvement.
• Develop strategies for leads that are not yet sales-ready, ensuring valuable prospects continue to be developed rather than lost from the buying journey.

• Evolve Sophos' nurture strategy from traditional, linear programs towards dynamic journeys driven by buyer behaviour, engagement, intent and account signals.
• Define the appropriate next-best engagement for prospects based on where they are in their buying journey.
• Partner with Content, Product Marketing, ABX and regional teams to ensure prospects receive relevant experiences throughout the lifecycle.
• Develop re-engagement and recycling strategies to reactivate prospects and accounts that have stalled or disengaged.

• Analyze performance across the funnel to identify where prospects are progressing, stalling or dropping out.
• Develop and test interventions designed to improve conversion, lead velocity and pipeline contribution.
• Partner with Marketing Operations and Revenue Operations to continuously improve lifecycle stages, lead scoring,…
